Spanish drink — it's okay for the French (4)
I believe the answer is:
cava
'spanish drink' is the definition.
(Spanish alcoholic drink)
I cannot understand how the remainder of the clue works.
(Other definitions for cava that I've seen before include "Spanish bubbly" , "Spanish sparkling white wine" , "Spanish sparking wine" , "sparkling drink" , "Sparkler" .)
